CLAMP OR FASTENING FOR CULTlVATOR-TEETH.

SPECIFICATION forming part of Letters Patent No. 671,677, dated April 9,1901.

' Application filed September 14, 1900- Serial No. 30,040. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN KILLEFER, acitizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements in Clampsor Fastenings for Cultivator-Teeth; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make andusethe same,reference being had to the accompanying drawings, and to theletters of reference markedthereon, which form a part of thisspecification.

The invention relates to means for securing the tooth of a cultivator tothe steel frame thereof, so that it may be conveniently ad justedvertically and the line of draft kept in a diagonal plane of thetooth-shank, the front of frame being on an angle of about forty-fivedegrees.

My invention consists of a tooth-clamp formed of a body, a clip, and twonuts, the construct-ion of said body being peculiar and of such acharacter as not to weaken the steel frame in any way whatever.

Figure 1 of the drawings is a side elevation of the invention. Fig. 2 isan edge elevation of the same. Fig. 3 is a plan of a modified body ofthe device. Fig. 4 is a reduced plan of part of a cultivator with thedevice in position.

In the drawings, A represents the steel frame of the cultivator, whichis V-shaped at front and rear, while the front and rear angle arebisected by the line of draft. A parallel plane to that of the draftmust pass diagonally through each tooth of the cultivator.

B is the body of the clamp, which is provided with the shoulders I) band the two clip-holes b b, arrangeddiagonally with respect to eachother. The body B of the clamp is fitted on the bar of the frame, sothat the latter will pass through the former between the shoulders, thesaid body B being made to fit snugly on the bar of frame. The clip 0 isthen placed diagonally over the tooth, whose rectangular form fitsnicely between the two shoulders I) b, and its arms 0 0, right angledand end threaded, pass through the bodyholes I) b. The nuts D are thenscrewed upon the ends of the clip-arms and the tooth E is securelyfastened to the frame A. It will be readily seen that the tooth can beeasily adjusted to project more or less below the frame,while the latteris marred or weakened in no way whatever,

Having thus described all that is necessary to a full understanding ofmy invention, what I claim as new, and desire to protect by LettersPatent, is

1. A coupling 'for cultivator or harrow teeth combined with thecultivator or harrow frame the said coupling being placed on theopposite side of the frame to that on which the tooth is placed andhaving lugs that extend over the frame to engage the tooth; whereby boththe tooth and coupling are secured to the frame by one piece, clip orplate and aV-shaped bolt substantially as shown and described.

2. A tooth-fastening for barrows or cultivators provided with twodiagonally arranged lugs and two diagonally-arranged holes, each lugbeing in the same horizontal "plane as one of the holes, the top holebeing arranged behind the tooth and the bottom hole in front of it, allsubstantially as shown and described, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN KILLEFER.
